Patent DE-4333908-A1 (DE)
Title: Analog/digital converter
Inventor: BRAUN CHRISTOPH
IPC: H03M1/50
Filed: 1993-10-05
Abstract: The invention represents an analog/digital converter method which is based on a novel pulse modulation with constant pulse amplitude. Since the signal spectrum is completely contained as band-pass signal spectrum in the pulse modulation spectrum, the invention provides for a novel circuit conception of an analog/digital converter which does not need any "sample-and-hold" circuit and manages without high-precision components. Utilizing the VLSI technology, the converter method according to the invention provides the opportunity for implementing analog/digital converters with minimum analog circuit expenditure. This provides for extremely linear conversion. The digital circuit section essentially consists of pulse counters and FIR filters which handle the digitisation and coding.

Title: Controlling access to redundant transmission channels in bus system
Inventor: BUCHHOLZ DIETER
IPC: G06F13/42
Filed: 1993-11-16
Abstract: The sending subscriber (1) transmits a message simultaneously over two channels (a,b) via separate lines (3,2) and receives on two other lines (4,5) for evaluation of starting and check symbols.

Advantageously the channel conveying the latest message is chosen for reception. Another message can be transmitted in response immediately after the conclusion of reception without interference with delayed messages on the other channels.

Patent DE-4418680-A1 (DE)
Inventor: STREIFINGER HELMUT
IPC: F02C7/228
Filed: 1994-05-28
Abstract: A fuel supply device 1 for a turbo jet engine with afterburner 2 has pipes 9 and 10 bifurcating from a main fuel pipe 7 for the supplying of fuel to the afterburner 2 and the combustion chamber 3. To deliver the fuel at the required rate of flow and at the required pressure, provision is made in the main fuel pipe 7 for a first fuel delivery pump 6, and for a second fuel pump 11 and respectively an afterburner pump 18 in the fuel pipes 9 and 10. In order also to be able to supply the afterburner 2 via the second fuel pump 11 when a suitably free pump capacity exists, downstream of the afterburner pump 18 and the second fuel pump 11 provision is made for a connecting pipe 19 between the two fuel pipes 9 and 10. When operating the turbo jet engine with afterburner, the afterburner 2 can be supplied by the second fuel pump 11 via the connecting pipe 19 when the fuel requirement of the turbo-combustion chamber 3 is reduced, so that its delivered quantity of fuel is high. An undesirably high fuel temperature downstream of the second fuel pump 11 can thus be prevented. An oil cooler 14 may be provided (various positions of correction being disclosed) as well as a 2/4 directional control valve in the connecting pipe (figure 2). <IMAGE>
